To all whom it may concern:

Be it known that I, ROBERT I do hereby declare the' following to be a full, clear; and. exact. descri tion of the same, reierence being .had to t e aecompanylng drawings, forming a part of this 'specific'as c outer element conslsts ofa number of hoops or bands '13 connected to the inner member tion, and to the reference-numeralsmarked thereon. I

My present inventionrelates to drying and evaporating machinery and it has for its objectto provide a simple and eifi'cient machineof large capacity for drying such substances as: fruits, grains and other vegetable 'productsby tumbling them about in a ourrent of dry air. Further objects of the invention' are to provide a machine that can be readillclea'ned' and which is adapted for both soli and liquid contents To these and 7 other endsthe invention resides in gcertain improvements and combinations of parts all 1 as will be hereinafter more fully-described the novel features beingpointed out in the claims at the end of the specifications.

senting in the present instance means for;

inolosing an atmosphere suitable for drying. In the chamber 3 I arrange arotary skeleton cylindercomprisingin the presentinstan'ee, inner and outer circular supporting elements 8 and 9, the formerof which consi'stsof a number of wheels or spiders on a shaft 11 mounted .in bearin-g s=12. Thethe is revolved to the left in Fig. 1, slowlyfby.

Between the supports '8 and-.9, the cylinder is provided-with inner andouter'sets of peripheral pockets 1:5 and 16 that receive 1 the material to be dried and-are adapted to empty it back and forth into each other as the cylinder is rotated. I-he'-pockets are-arranged inpairs consisting-of units of each I set radially alined but the inner pocket-of 'onepairdelivers to; and receives from the outer pocket of the adjacent pair for thereason that thejfpairs of pockets mentioned are formedintegrally from aqsingle sheet of material bent-in'to -the form. of an S, .as shown-Lin Figs, 1 and. 3,

These trough shaped membersextend longitudinally of the-periphery of the cylinder and are-bolted to the outer supporting bands 9 at 17 and, I

'to the inner supporting wheels :8 at 18 and a they are also'spaced from each other so-that lips of j the pockets that the inner i one of -a pair ,overhangs and delivers to the 'up'perone of the pairto the left on the down tri 1' and I the lip of the latter overhangs and de iyers to the first mentioned inner ocketf-jon the upward movement. Thus, int e posltion A,

.Fig. 1, the material is in the inner pocket 15. When the position B is reached, the material.

is dumped into the outer pocket 16' -and when the position (1 is reached, it i's-dumpedback into the inner pocket 15. ,In-no is the material directed otherwise or permitted to escape and as it is poured back andforth it is traversed by the current of .air passing between the troughs or pairs of poo ets;

The cylinder may be sealediat the ends, particularly when uicy or liquid materials are being treated, by disks and suitable alined doors 21 in these disks permit the contents to be pushed out of each pair ofpockets when dried into a chute 22 through the use of a suitable implement, and the troughs or pockets may also be cleaned in this manner.

I claim as my invention:

1. A drier comprising a rotary cylinder adapted to permit the free transverse circulation of air and having inner and outer sets of peripheral pockets adapted to empty back and forth into each other as the cylinder is rotated, air openings being provided between the pockets. i

2. A drier comprising a rotary cylinder 7 having inner and outer sets of peripheral pockets, said pockets beingformed in pairs composed of a pocket in each set radially alined and the inner pocket of one pair and the outer pocket of an adjacent pair being adapted to empty back and forth into each other as'the cylinder is rotated.

3. In a drier, the combination with a cylinder having inner and outer circular sup- Tp'orts, of a plurality of integral troughs mounted between the supports to form inner and outersets of pockets adapted to empty.

back and forth into each other as the cylinder is rotated. 4. In a drier, the combination with a cylinder, of a plurality of substantially S- sha-ped troughs vmounted longitudinally of the periphery of the cylinder and formed from integral sheets 'or plates to provide inner and outer sets of pockets, the inner pocket of one trough and the outer pocket of the adjacent one being adapted to empty back and forth into each other as the cylinder is rotated.

5. In a drier, the combination with a cylinder having inner and outer circular supports, of a plurality of substantially S- shaped and relativelyspaced troughs mounted longitudinally of the periphery of the cylinder between the supports to provide inner and outer sets of pockets, the inner pocket of one trough and the outer pocket of the adjacent one being adapted to empty back and forthinto each other as the cylinder is. rotated, the troughs being secured to both supports, and radial spokes connecting the latter and located between the troughs.
